"Lemon of Troy" is the twenty-fourth and penultimate episode of the sixth season of the American animated television series The Simpsons.
Bart leads Milhouse, Nelson, Martin, Todd and Database to Shelbyville to find the tree and return it to Springfield.
The fathers and sons demand their tree be returned, but the owner of the impound lot taunts them and refuses to surrender it.
When night falls, the Springfield men and boys emerge from the RV and tie the lemon tree to its top.
In Shelbyville, an old man makes up a story about the tree being haunted to cover the embarrassment of losing to their rivals in Springfield.

The scene where Milhouse envisions himself using his camouflage clothing to taunt the Shelbyville kids, leaving only his smile and glasses visible, references the Cheshire Cat from Alice In Wonderland.

Club, David Sims writes that "The 'rival opposite town' is a TV trope that feels very standard at this point, so it’s hard to remember that The Simpsons pretty much invented it.
